If I understand this correctly, you want to fill a listbox
with buttons, and have those buttons belong to some group manager.
What about "com.sun.java.swing.ButtonGroup"?   

Or, why not model your approach after that of the JBCL "CheckboxPanel" 
which essentially adds the "itemMulticaster" to each of the elements 
in the panel?  The "CheckboxPanel.addItemListener()" method adds
a listener to the "itemMulticaster".  The effect is that when 
the item state is altered, the item multicaster is notified and
it in turn notifies the component that was registered as a listener, 
e.g., your frame.
